Resumo: In agricultural crops is common planting the main crop on the remains of straw harvesting the crop earlier due to no-tillage system. The straw remaining in the soil can exert positive or negative influence on the main crop through the release of organic compounds that carry allelopathy on plants of the subsequent growing. This experiment consisted of mixing and blending of different types of turnip (Brassica rapa L.), oats (Avena sativa L.), crambe (Crambe abyssinica Hochst. Ex RE Fries), Safflower (Carthamus tinctorius L.) and rapeseed (Brassica napus L . var) in soil and placed in plastic trays where they planted the seeds of maize. The experimental design was completely randomized design with six treatments and three repetições. As ratings were: emergence, rate of emergence, shoot length, root length, root dry weight, dry weight of shoots. The cover crops canola and safflower showed a positive effect, as crambe, turnips and oats had a negative effect on initial growth of maize seedlings, are not suitable for cover crop to maize sowing.

A palhada remanescente no solo pode exercer influência positiva ou negativa sobre a cultura principal pela liberação de compostos orgânicos que exercem alelopatia sobre as plantas da cultura subsequente. Este experimento constou da mistura e homogeneização das palhas de nabo (Brassica rapa L.), aveia (Avena sativa L.), crambe (Crambe abyssinica Hochst. ex R. E. Fries), cartamo (Carthamus tinctorius L.) e canola (Brassica napus L.var) no solo, que foi colocado em bandejas plásticas onde semeou-se o milho.  O delineamento experimental foi inteiramente casualizados com seis tratamentos e três repetições. As características analizadas foram: emergência, índice de velocidade de emergência, comprimento de parte aérea, comprimento de raiz, massa seca de raiz, massa seca de parte aérea. As coberturas vegetais canola e cártamo apresentaram efeito positivo, já crambe, nabo e aveia tiveram efeito negativo sobre o crescimento inicial de plântulas de milho, não sendo indicadas para cobertura vegetal para semeadura do milho.UEL2011-07-12info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionAvaliado por paresapplication/pdfhttps://ojs.uel.br/revistas/uel/index.php/semagrarias/article/view/347110.5433/1679-0359.2011v32n2p577Semina: Ciências Agrárias; Vol. 32 No. 2 (2011); 577-582Semina: Ciências Agrárias; v. 32 n. 2 (2011); 577-5821679-03591676-546Xreponame:Semina.
